Cervical cancer is the second most common female cancer in the world. In Korea, cervical cancer accounts for 13 percent of female cancers and 4,200 cases occur annually[1]. The purpose of this study is to use a deep learning model to identify the possibility of lesions in the cervix and to evaluate the efficient image preprocessing in order to diagnose diverse types of cervix in form. The study used 4,107 normal photographs of uterine cervix and 6,285 abnormal photographs of uterine cervix. Two types of image preprocessing were resized to square. The methods are cropping based on height and filling the space up and down with black images. In addition, all images were resampled to 256×256. The average accuracy of cropped cases is 94.15%. The average accuracy of the filled cases is 93.41%. According to the study, the model performance of cropped data was slightly better. But there were several images that were not accurately classified. Therefore, the additional experiment with pre-treatment process based on cropping is needed to cover images of the cervix in more detail.

Background:Cervical cancer is potentially the most preventable and treatable cancer. Despite the known efficacy of cervical screening, a significant number of women do not avail themselves of the procedure due to lack of awareness. Objectives: This study was conducted to elicit information on the knowledge, attitude and practice (KAP) regarding screening (Pap test) and vaccination for carcinoma cervix among female doctors and nurses in a tertiary care hospital in Bangalore and to assess barriers to acceptance of the Pap test. Materials and Methods: A cross-sectional, descriptive study was conducted with semi-structured, self-administered questionnaire among female health professionals. The study subjects were interviewed for KAP regarding risk factors for cancer cervix, Pap test and HPV vaccination for protection against carcinoma cervix. Results: Higher proportion of doctors 45 (78.9%) had very good knowledge as compared to only 13 (13.3%) of the nurses, about risk factors for cancer cervix and Pap test (p=0.001). As many as 138(89.6%) of the study subjects had favorable attitude towards Pap test and vaccination, but 114 (73.6%) of the study subjects never had a Pap test and the most common reason 35 (31%) for not practicing was absence of disease symptoms. Conclusions: In spite of good knowledge and attitudes towards cancer cervix and Pap test being good, practice remained low among the study subjects and most common reasons for not undergoing Pap test was absence of disease symptoms. The independent predictors of ever having a Pap test done was found to be the occupation and duration of married life above 9yrs. Hence there is a strong need to improve uptake of Pap test by health professionals by demystifying the barriers.

Objective : This study was aiming at estimating the joint effects of various risk factors associated with uterine cervix cancer in Korea. Methods : Data obtained from a case-control study were analyzed with a multiplicative model. Results : After adjustment for age and husband's educational attainments, the family history of cervical cancer (OR=2.1, 95% CI=1.2-3.9), unstable marital status due to separation, by death or divorce, etc. (OR=2.8, 95% CI=1.7-4.6), and a large number of deliveries ($\geq$3 vs. nulliparous OR=6.5, 55% CI=1.4-29.0) increased the risk of uterine cervix cancer, Conversely, first sexual intercourse at an older age ($\geq$25 years vs. <19 years OR=0.4, 95% CI=0.2-0.6) and husband's circumcision (OR=0.7, 95% CI=0.5-1.0) decreased the risk. In the multiplicative model, the highest joint risk (OR=39.2, 95% CI 5.9-258.9) was observed in women with a family history of uterine cervical cancer, an unstable marital status, where the ex-husband was not circumcised, with 3 or more delivery experiences, and having her first sexual intercourse when younger than 19 years of age. However, women without a family history of uterine cervix cancer, married to a circumcised husband, having had her first sexual intercourse at 25 years or older, and nulliparous, showed the lowest joint effect (OR=0.3, 95% CI=0.1-0.5). Conclusion : As carcinogenesis is a complex action involving various factors, we consider a joint effects approach to be appropriate in an epidemiological study on risk factors for uterine cervix neoplasms cervix neoplasm.

Signet ring cell carcinoma is a rare type of mucinous adenocarcinoma of the uterine cervix. To the best of our knowledge, there is no report on cytologlc findings of primary signet ring cell carcinoma of the uterine cervix in the literature. Recently, we experienced two cases of signet ring cell carcinoma of the uterine cervix. The finding of characteristic signet ring cells on cervicovaginal smear led to the diagnosis of signet ring cell carcinoma. However, primary signet ring cell carcinoma could not be cytologically distinguished from more common metastatic tumor. Therefore, diagnosis rests upon the recognition of signet ring cells and the absence of signet ring cell carcinoma elsewhere.

Whlie cytologic characteristics of squamous dysplasia, carcinoma in situ, and invasive squamous cell carcinoma of the uterine cervix are well documented, relatively few studios have dealt with the cellular features of microinvasive carcinoma. In order to describe the cellular characteristics of microinvasive squamous cell carcinoma, we retrospectively reviewed 45 cervovaginal smears(15 carcinoma in situ, 15 microinvasive cancer, 15 invasive cancer) which were confirmed by histologic examination of specimens obtained by hysterectomy at the Seoul National University Hospital during S years from 1995 to 1999. The cytologic features about tumor diathesis, inflammatory background, ceil arrangement, anisonucleosis, nuclear membrane irregularity, nuclear chromatin pattern, and nucleoli were observed. The cytologlc characteristics of microinvasive squamous cell carcinoma of the uterine cervix are syncytial pattern, mild tumor diathesis, the irregularity of nuclear membrane, irregularly distributed nuclear chromatin, and occurrence of micronucleoli. But, correlation between the depth of Invasion and the cytologic feature had limited value.

We present the cytologic features of small ceil neuroendocrine carcinoma of the liver metastasized from the uterine cervix. Cytologically, tumor cells were arranged in a pattern of solid sheet in necrotic background. The tumor cells were characterized by uniform, small cells, round hyperchromatic nuclei, and high nuclear cytoplasmic ratio. The smears showed frequent mitotic figures and rosette formation. These findings were identified with the previous histologic sections of uterine cervix. To make a diagnosis of metastatic small ceil neuroendocrine carcinoma on the Papanicolaou smear, a high index of suspicion and careful review of clinical history are needed.

Glassy cell carcinoma is an unusual neoplasm of the uterine cervix with highly aggressive clinical behavior. On cervico-vaginal smear examination, the tumor has well confused of atypical repair ceil of the endocervix. Recently, we have experienced two cases of glassy cell carcinoma of the uterine cervix, diagnosed on cervico-vaginal smears and confirmed on fellowing histologic sections. The cervico-vaginal smears revealed abundant clusters with well defined boarders. The cell clusters were composed of large tumor cells. The tumor cells had distinct granular cytoplasm and eosinophilic macronucleoli, Characteristic cytologic features of this tumor were discussed in view of differential diagnosis.

Background : Cervix cancer is the most common form of cancer among Korea women. in spite of proof that cervical cancer screening could reduce death rates substantially, the screening rates reported by previous Korean studies remain stubbornly very low. Behavioral studies to increase the cervix cancer screening rate are essential in order to develop the cancer screening program. Objective : To evaluate the factors which are related to the intention and behavior for cervix cancer screening using the Theory of Planned Behavior (TPB) and the Theory of Reasoned Action (TRA). Methods : The survey was conducted from July 21 st to 26th in 1998. Of 3,218 women, 303(12.2%) between 30 and 55 years old, voluntarily participated in the survey in the 3 Myeons in Choongju city. Charge-free cervix cancer screening was provided for the subjects 3 months later. Results : The R-square of both TPB and TRA to the intention (30% and 42%, respectively) was greater than the actual behavior (21% and 13%, respectively. TPB and TRA were found to provide an appropriate framework for the study of cervix cancer screening behavior. However, TRA was more powerful in explaining the intention, not only because the perceived behavioral control component exhibited lower reliability and validity than other components(altitude and subjective norm), but also because there may have been a few limitations in this study design. Consequently, the use of TRA is preferred in attempting to explain intention and actual behavior in this study. Conclusions : This study suggests that a successful intervention program should focus on changing attitudes and reducing psychologic barriers, rather than on just providing information. Physician recommendations, and the support of family members and friends are also very important factors in cervix cancer program participation. Physicians, friends, family members, and opinion leaders in rural areas, all of whom could affect the individual subjective norm, may all have the potential to play great roles as facilitators.

Small cell neuroendocrine carcinoma of the uterine cervix is a distinct subtype of cervical cancer that appears analogous to oat cell carcinoma and carcinoid tumors of the lung. It has been assumed to be derived from the neural crest via argyrophilic cells in the normal endocervix. We have recently encountered a case of small cell neuroendocrine carcinoma of the uterine cervix coexisting with adenocarcinoma which was argyrophil negative. A 66-year-old multiparous woman was admitted because of vaginal bleeding for 2 months. Cervicovaginal smear revealed several scattered clusters and sheets of monotonous small cells with some peripheral palisading in the background of hemorrhage and necrosis. Radical hysterectomy specimen revealed an ulcerofungating tumor on endocervical canal which was composed of two components. Major component of the tumor was made up of monomorphic population of small oval-shaped tumor cells arranged in sheets and partly in acinar structures or trabecular fashion. Other component was adenocarcinoma, endocervical well-differentiated type. Argyrophilia was present on the Grimelius stain and immunohistochemical studies revealed diffuse positivity to neuron-specific enolase and carcinoembryonic antigen. Electron microscopic examination showed clusters of small round to oval cells, which had a few well-formed desmosomes and several membrane-bound, dense-core neurosectetory granules.

Glassy cell carcinoma is an unusual neoplasm of the uterine cervix that accounts for $1{\sim}2%$ of all cervical malignancy. It is a rapidly progressive and biologically aggressive disease with poor response to therapy. This tumor is considered to be a poorly differentiated mixed adenosquamous carcinoma. The cytologic findings are characterized by tumor cells arranged predominantly in syncytial like aggregates and an inflammatory background. The tumor cells have moderate amounts of eosinophilic or amphophilic cytoplasm, which is often finely granular. The nuclei are relatively large and have fine chromatin with prominent eosinophilic nucleoli. Cytologically, glassy cell carcinoma is most likely to be confused with large cell nonkeratinizing squamous cell carcinoma and with atypical reparative cells. Herein, we report three cases of glassy cell carcinoma of the uterine cervix diagnosed by cervicovaginal smear and confirmed by histologic section with review of literatures.
